Advances in Deficit-Regulated Irrigated Potato Research

Potato is one of the most important food crops worldwide, and its yield and quality are directly affected by irrigation management. Loss-in-adjustment irrigation is a water-saving and efficient irrigation strategy, which stimulates plant root development and improves water use efficiency by reducing the amount of irrigation during specific periods of the crop growth cycle, thus realizing the purpose of saving water and increasing yields. The purpose of this paper is to summarize the research progress on deficit-regulated irrigation in potato in recent years, to explore its impact on potato growth and development, yield formation, and quality enhancement, and to suggest potential avenues for future research.
